8428.20.00 - Pneumatic elevators and conveyors

HTS Code 8428.20.00 encompasses pneumatic elevators and conveyors designed for the movement of goods or materials. These systems utilize compressed air to facilitate the lifting or continuous transportation of items within industrial or commercial settings.

This category is distinguished from its siblings by its exclusive reliance on pneumatic power. For example, 8428.10.00.00 covers passenger or freight elevators that are not continuous-action and skip hoists, which may operate through different mechanical principles. Similarly, 8428.40.00.00 deals with escalators and moving walkways, and 8428.60.00.00 pertains to teleferics and ski lift systems, none of which are driven by pneumatic mechanisms.

The subcategories within 8428.20.00 further refine classification based on the specific function of the pneumatic machinery. 8428.20.00.10 is designated for pneumatic conveyors, which are typically employed for the horizontal or inclined movement of bulk materials or packaged goods through a system of tubes or enclosed pathways. Conversely, 8428.20.00.50 is reserved for pneumatic elevators, which are designed for vertical lifting operations, often involving sealed chambers or suction-based systems to raise goods to different levels.
